Abstract

The large number of potentially hazardous analytes in environmental samples requires methods of analysis which can yield specific information when applied to extremely complex mixtures. The emergence of GC/FT-IR techniques for environmental analysis offers the possibility of confirmation of GC/MS results and, in some cases, the possibility of complementary information, particulary in the case of isomers. In order to achieve a higher level of confidence in the identification of aromatic compounds found in environmental samples, it is necessary to use techniques which are sensitive to the position of substitution and functional groups. This paper reports the results obtained from the combined GC/MS and GC/FT-IR identification of aromatic compounds found in a marine sediment.
